For centuries, Cosmos has been the butt of many a joke - being the "weird" minibot isn't fun. He secretly longs to be a strong warrior and get revenge on his fellow minibots who have mercilessly taunted him over the years.

During a voyage into a previously unexplored star cluster, he picks up a faint signal that he traces back to an abandoned Decepticon lab on a small planet. There he discovers a form of combiner technology previously unknown - microscopic nanobots that can infest a group of hosts and alter their bodies to combine, all under the control of whoever programs them.

He returns to Autobot HQ with the nanobots that he has programmed, and secretly introduces them into himself and some of the other minibots he despises most. Unknown to the chosen, their bodies are being subtly altered in ways they can't imagine, subconsciously awaiting the day when Cosmos utters a secret command over a secure communications channel to them all - that command is COSMONAUT.

An idea I've been kicking around for a few days has finally begun. I've still got some joint work to do, but this is the basic idea. They needed very few mods to combine this way, no extra parts or partforming needed (except maybe a combiner head). Alt and robot modes remain unaltered.

I can't decide if I should add a combined head or not - story wise, he doesn't really need it. If I do add one, I'm thinking a larger version of Cosmos's head, or some kind of clear one that would represent a hologram that he creates.

Already it's a better body shape than any 80's combiner. Very creative - and great idea to make Cosmos the head/centerpiece - gives a nice heroic barrel chest/pecs/shoulder shape. Personally, I don't think you need to add a bigger head. It's entertaining to see his actual Cosmos head - and with it's small scale it makes the gestalt feel massive. Smaller head=bigger illusion of scale. Keep it as is IMO.

Too friggin' sweet! As far as the head goes, I'm torn. I love the idea of the holographic-but-bigger cosmos head, but I also already like the way cosmos' regular head looks on the combiner mode. I'd say go for it, and...
maybe every once in a while his holo-projector acts up and he has to go "tiny-headed".
